Robbins will play Conklin, a sadistic and ruthless member of Shadowspire who will be an adversary for Oliver (Stephen Amell) in the flashback sequences. The show’s flashback arc will also see the titular hero take on Jimmy Akingbola’s Baron Reiter (aka Baron Blitzkrieg in DC Comics Canon), who is the leader of Shadowspire.

We’ll see how much more difficult Oliver’s 4th year of his 5 year disappearance is going to be compared to the first three years, and we’ll find out when season four of “Arrow” returns on October 7th.
